If I already put intake and headers and all that stuff.. And then I want to swap to engine to a h22a1 do I have to buy all of it all over again??

 

Yep.

 

not the intake, well at least i didnt. the headers you do. the bolts dont match up. Ive heard though that the intake for the accord is 2.5" and the h22a 3"............

 

I think you need the 3"... I hear the h22 will run too rich with a 2.5" or stock accord intake.

 

yeah i dont know about all of that. I just used my accord AEM one because i didnt even think about the piping when i did my swap, but whenever I look at my plugs, they dont look rich at all. So, who knows. Probably should go with the h22a one, but I dont know if the bracket will fit into the accord chassis in the right place...

 

you can use the intake from the accord, it will run rich but you will retain a certain amount of tourque with the accord intake that you would lose with the prelude intake...but in my opinion you should go with one from the prelude...

 

I made my own intake for my H22a, 3" exhaust piping from JC whitney, some big gromets from Home Depot and a filter and I had an intake for about $75.

 

dude you have an h22 now? sweet man!
